Making a wide base rear cog

Let me just start off by saying yes, I am a cheap SOB. Now lets get down to business.

Has anyone tried riveting or otherwise attaching smaller cogs on either side of a Shimano BMX cog to widen it? This is to prevent it from digging into the freehub body. Yes, I could just drop $30 on a King cog every other month, or I could just drop $5 on a new BMX cog. I am basing this on how fast I go through cassettes, since I am new to SSing.

I figured I could just grind down the teeth on a old cassette cog or even new BMX ones until I had say 1/2" tall rings. I could then just rivet or bond these on either side.

You can afford an alloy freehub body, but you can't afford wide base cogs???
If you are using a steel freehub body, you don't need a wide base cog.

Seems like your cheapness is spoiling things for you. Live a little, eh?
My King cog (steel) lasted me about 4-6 months max.
My Boone Ti is finally giving up the ghost at the 1 year point.
Of course, you'll whine, complain, stamp your feet...."$60 FOR A COG?," as you cheap dudes will do...
But you won't have to think about it for another year at least..you'll be glad you did.

Also, you could get even more than a year if you weigh less (torque less) than I do at 250lbs.

Like what? Ice cream?
Isn't riding something you are passionate about? In my book, that makes it worth it.

Like more bikes...need to get a road bike.
Plus, like I said, I am new to SSing. So, if this gear ratio works for me, maybe I will buy a king down the road, or invest in a SS specific hub/wheel. I am very passionate about riding, but I am also passionate about not going into debt over it.

It is about macgyvering, and it is fun. If I can make or modify my own parts, it is what makes my bike mine. It is also people tinkering like this that leads to inovation. Granted, this example is nothing special. What if Chris King never decided to try to build his own headsets and hubs? You can only ride for so long when it is -10 F outside. I need something to keep me busy.

Waisting $60 for a $5 cog. You could but 10 to 12 Dx cogs. This guy might want to spend the extra $55 on his family or other projects. Why throw your hard earned money on something that will wear out. Sorry about the bling.

undefinedMcgyvering is sooo fun, just don't get cheesed off when your creation doesn't work so hot (i sometimes wish real life was like TV ,then It would all work out in the end And you'd get the girl)

Something similar

I have a sandwich of cogs and spacers from a cassette, held together with split pins. These are pins in the shape of hollow cylinders that are split along their length; they look like a little square of steel rolled into a cylindar. My sandwich consists of 4 spacers, a drive cog and two cut down cogs acting as steel spacers. I found pins (at local big box hardware store) that tap into the 3 holes in the spacers and cogs and hold the sandwich together securely.

Split pins are a great idea. These would ensure a nice tight fit so that the pressure is distributed across all the cogs/spacers.

Padre, you are a Clyde + 50?

"Cheap SOB's die sad and discontent."

Damn Padre, no wonder why you go through so much bike stuff, put down the weights already eh.

cog plus 2 spacers

Get 2 cheap steel spacers put a cog in between and weld/braze them together. Result is a cheap reasonably durable wide base cog. Or, contact Walt, that's who I heard the idea from and he may sell them, or maybe only to people who buy a bike from him.

Good, simple, inexpensive idea. Not all of us live in Cali and have money to through around.
